What size battery do i need for my 96 dodge ram 5.9 gas? cca? ah?

It will work fine. The CCA is a rating of how much power that the battery is capable of delivering at once and as the name suggests, cold cranking amps, is needed more in cold temperatures. As long as you are not in the arctic, it should be fine for a couple of days.

Size 24 or 27. I found this on the AutoZone website. You can too.
Good luck!

Check to see if it is not your 'idle speed motor'. About the size of your thumb on the back side of the throttle body. Also, and I know it sounds simple, check your air cleaner.

Your starter will draw what it needs from the battery. The extra reserve in the battery won't be used except under adverse conditions, when you'll be glad you have it. Besides physical size and weight, that should not be a problem.

Run fault codes checking for canister purge solenoid/valve Check fuel system pressure and pressure regulator.

Whatever you want to buy or pay for

The parts store will tell you the Group Size

You then pick the CCA

Higher CCA cost more,last longer & have better warranty

-Possibly the battery is not strong enough to crank. Try high
CCA battery. For example now the one you have has CCA 750
How about change to the maximum that they carry.

Good luck

HI. This vehicle only requires a maximum of 750 cranking Amps; ((640 Cold)). A regular name brand Gold-Duralast 12 volt cell will be sufficient for this vehicles needs.

That battery is big enough. I would look at the starter. try hitting the starter with a hammer,pipe or steel rod. Hit the starter not the solenoid. Then try starting it. if it starts turning better or starts the engine, replace the starter. If that doesn't work let me know and we can go from there.

Just as a general rule of thumb, I don't buy a battery with less than 700 CCA (cold cranking amps). Depending on where you live, it may need to be more or less. Check your old battery (if you have it) and see how many CCA it has.
